Simulation of LEACH Protocol Implementation in MATLAB

We conducted simulation research on the LEACH protocol using MATLAB. LEACH (Low-Energy Adaptive Clustering Hierarchy) is a fundamental clustering protocol widely investigated and applied in wireless sensor networks. The core algorithm involves partitioning network nodes into multiple clusters, where each cluster is managed by a cluster head responsible for data collection and transmission. In our MATLAB implementation, we developed functions for cluster formation, cluster head selection using randomized rotation, and energy-efficient data routing. The simulation framework incorporated various network topologies, node densities, and transmission ranges to comprehensively evaluate protocol performance through metrics like energy consumption analysis and packet delivery ratios. Our research findings demonstrate that LEACH achieves excellent energy efficiency and high data transmission reliability, making it a valuable clustering protocol worthy of broader adoption. The MATLAB code includes key components such as energy calculation modules, cluster head election algorithms using round-based thresholds, and inter-cluster communication handlers for realistic network behavior simulation.
